LAWN SPRINKLER.

Application filed June 1, 1927. Serial No. 195,707.

the head being such that when the parts are arranged in one position thewater will be discharged in a circular spray. V In utilizing theordinary type of sprinkler for lawns or gardens, such sprinklers throwthe water on a path, sidewalk or roadway, this being disagreeable forthe passcrsby, as well as wasting the water. With my improved sprinkler,the proper sprinkler head may be'chosen to throw the water to dropparallel to paths or sidewalks and to dischargew'ater on a parkwayparallel-to a sidewalk and roadway.

.Another important object of the invention isthe provision of asprinkler-head which is adjustable so that the proper spray may-beobtained in case of vanation in the pressure of the water. supply and sothat either a qoarse or a fine spray may be ob- T tained... l v

Another object is the provision of a sprinklerhead of this characterwhich is so 1 constructedthat-when properly adjusted the flow of watertherethrough will be cut off, the advantage or this being that in casesplurality of the sprinkler heads-are used in connection with a buriedirrigating pipe,

any one or more of them may be cutout without interfering in any waywith the operation of the remaining-ones. Another object is theprovision of a sprinkler head of this character WhlChdS so constructedthat the water will rise higher into the air before being converted intospray, this feature being "important inasmuch as'ittends to prevent theformation of a puddle in the immediate vicinity of 'the sprinkler head.1

An' additional objectisthe provision .of a device of this characterwhich will be extremely simple and-inex nsive in manu---fa'cture,=easi1y converted om one form for roduclng a circular-sprayinto. the other orm for producing a strip spray, and to 'athird form ifso desired, to produce a semi-circular spray, which will be highlyeflicient in use, durable in service and a general improvement art.

With these and many other objects in through. I

view which will morereadily appear as the nature of the'invention isbetter understood, the same consists in the novel construction,combination and arrangement of parts, which will hereinafter be morefully described, illustrated, and claimed.

The essential features of the invention involved in the. carrying out ofthe objects indicated are susce tible to modification; but a preferred'em, odiment of the invention is shown in the accompanying drawings, inwhich:

PATENT OFFICE.

Figure 1 is atop plan view of the device showing the same'in assembledrelationship when a circular spray. is desired.

Fig. 2 is a. sectional view taken substantially along the lines 2- 2 ofFigure 1.

-Fig. '3 is a sectional view taken substantially along the lines 3-3 of-Figure 2.

' Fig. 4is a view similar to Figure 1, showing the partsv in assembledvrelationship when a semi-circular spray is desired.

" Fig. 5 is a sectional view taken substantially along the lines 5-5 ofFiguret, and Fig. 6 is a sectional view of a still further arrangementofparts that are contemplated when a vertical strip spray is required.

The various figures described above adequately illustratev my invention,and the followin detailed description is commensurate with t e abovementioned drawings in enabling an artisan to construct and assemble theconstituent parts of the same.

Referring more particularly to the drawings' and especially tie-Figures1, 2 and 3, my vsprinkling device comprises a body 10 preferably ofcylindrical form having a tion 13 shown in dotted'lines in Figure 2,

and the upper end of which is provided with a valve seat 14. When mysprinkler is mstalled, it is designed that the top of the portion 11 beflush with-thesurface of the ground so that when the lawn is cut thesprinkler-will not be in the way of a lawn mower or the like. 'A' web 15is provided within 'the'body portion 10, which web has a threadedaperture 16 extending there- Screwed within the upper portion of thebore 12 is a bafile mem er formed'as of a conical disc 17 having aconical seat 18 on the under side thereof. This bafile member isprovided with a reduced shank 19 threaded as at 20 to be received Withinthe threaded portion 16 of the web 15. This 5 discis provided with ahead 21 having a ternal marginal flange is provided above the web 15 fora p'u'rnoseto be described hereinafter. Y The operation of this form ofthe device is as follows:

Assuming that a circular spray is des red, the bafie member 17 isscrewed into position in such a manner as to obtain the desired Ithickness of spray. If a thin spray 15 demag-ace insure full protectionto the building by keeping the same dry so that the plaster of the samewill not become damaged through sediment or rust that may lurk in thepipes.

The formshown in Figure 6 is. adapted for use when a vertical spray isused as between sidewalks in a park or between buildings that are closetogether and the like. In this case, a small cup designated as at 17" isfrictionally inserted within the recess in the body member 10. Thissmallcup 17" has an outwardly extending annular flange 18" and a slot 19 isformed within the same so that water issuing from the pipe 13 will passaround andthrough the spider 15 and through the slot 19 where it will beprojected upwardly, forwardly and rearwardly in the shape of a narrowWeb.

sired, thebaflie member 17 may closed upon the valve seat 14 to such aposition as to obtain a narrow circular outlet for fluid;

From the foregoing description and a study of the drawings it will beapparent that I have thus provided a very simply 45 the tubular member.

50 180 'aroun and if a thicker spray is desired, the baflle member 17may be elevated from the valve seat 14. -When water is turned on in thepipe 13, the same will pass around the web 16 a the internal annularflange 30 and ou tv ari ily between the valve seat 14 and the surface 18in the form of a conical spray.

. This form of the device is particularly useilll ful for irrigatinglarge areas of lawn, flowers, shrubbery and the -l1ke.

When it is desired to form a spray of semi-circular form, the deviceshown in Figures 4 and 5 is employed. The same bod 35" portion 10 isused, but the bafiie member 1 is removed and a modified form of bafllemember 17' is substituted therefor. TlllS member comprises a tubularmember 20 which is firmlyfi pressed Within the depres- 40 sion in thebody portion IO-and rests against the flange 30 where it is heldfrictionallym position. The tubular member 20 is in; ternally threadedas at 21 and a plug having threads thereon 1s dlsposed within The plug22 has a conical surface 23 and a conical valve seat 14 is formed withinthe tubular'member. A slot 25' is out within the side of :the tubulamember and this slot may be out either d the tubular member, or more orless as may be desired. Adjustment of the plug 22 will secure the roperdegree of thickness of the. spray. his 'devlce 1 s particularly usefulwhen it is desired to llll- 66 gate lawns adjacent the side of abuilding or the like, and the spra may be directed outwardly from thebuil ing so that water may not be thrown against the building where itwill trickle down the s1de of the (W same and form puddles adjacent thebuilding. Furthermore, this'type of spray will constructed andconsequently inex ensive sprinkler head which is convertible or useeither in producing .a circular spray or a strip like spray, the devicetherefore having the great advantage of being capable of use under awide variety of circumstances. Owing to the simplicity it is to beobserved that there is practically nothing to get out of order and thatthe device should consequently have an extremelylong life.

' While I have shown and described the preferred embodiment of theinvention, it is of course to be readily understood that I reserve theright to make such changes in the form, construction and arrangement ofparts as will not depart from the spirit of the invention or the scopeof the subjoined claim.

Having thus described my invention, what I claim, is:

A sprinkler comprising in combination a body portion having a passagetherethrough terminating in a cylindrical discharge opening, a web insaid passage, a conical valve seat flaring from said discharge opening,a baflie member comprising a conical head and a shank removably carriedby said web. and adjustable to position said head with respect to saidseat, and an annular flange in said passage between said dischargeopening and web and cooperating with-the wall of said discharge openingto form a seat for the reception, on removal of said conical head andshank, of any one of a plurality of variant nozzles, each having itsinlet end sha ed to be frictionallyre'celved and retained in thedischarge opening against the flange.

In testimony whereof I have signed my name to this specification.
